I'm looking to buy a center channel speaker, for hopefully under $100. I have recently purchased the SS-F6000 speakers from Sony. I was looking at the SS-CN5000, and the Klipsch Synergy C-1. I've read many places you want to match the fronts and center speakers, but it is really that important? The Klipsch is on sale right now for $79, and the Sony is at about $70. Any suggestions will be great
